Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Summarize the paragraphs taken from this recent article. Refer to this specific text:

New studies show that gas stoves are worse for the environment than previously thought, and contribute directly to global warming because they constantly leak small amounts of methane even while they're turned off. Gas stoves can also emit high levels of nitrogen oxides, which raises public concerns about health impacts and air quality indoors.

"Changing the ways we make and use energy to decrease our reliance on fossil fuels will help ensure a healthier environment for us and our children," New York Assembly Speaker Carl E. Heastie said in a statement. 

But for those worried this new legislation could impact their beloved existing kitchen power, Hochul had some words of relief: existing buildings will not be impacted by the new legislation. "Everybody who has a gas stove, enjoy it. Keep your gas stove," said Hochul to FOX 5. "Nobody's touching your gas stoves!"
Response: Gas stoves have been shown to harm the environment, contribute to global warming, and create an unhealthy home environment, by releasing high levels of toxins into the air even when not in use. Many are worried about their existing gas stoves being impacted by this new law but Governor Hocul reassured the public that they will remain in place and will not be affected.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the following excerpt:

Renewable energy sources, such as wind and solar, have seen exponential growth over the past decade. This trend is a result of decreasing costs, technological advancements, and increased awareness of the need for sustainable energy solutions. Governments worldwide are implementing policies to encourage the shift from fossil fuels to renewables, aiming to combat climate change and promote energy independence.
